In this work, we have synthesized copper oxide nanoparticles using Iranian violaceae flower extract and explored its biological activity. Green synthesis has emerged as a reliable, sustainable and ecofriendly protocol for synthesizing a wide range of nanomaterials and hybrid materials. In this paper, we report the synthesis of Copper oxide nanoparticles by a simple biological route using the extract of Iranian violaceae flower and CuSO4, 5 H2O was used to synthesis the copper oxide Nanoparticles. The synthesized copper oxide nanoparticles were characterized using UV–visible spectroscopy, FTIR spectroscopy, FESEM, EDAX, and XRD techniques. UV –Visible analysis shows a characteristic peak around 266 nm for copper oxide nanoparticles and which is characteristic copper oxide nanoparticles. FTIR spectroscopy was used to characterize various capping and reducing agents present in the plant extract responsible for nanoparticle formation. The surface morphology was characterized using FESEM. The EDAX and XRD pattern suggested that prepared copper oxide nanoparticles were highly pure. The average particle size was calculated as 78.5 nm and α-copper oxide for all diffraction peaks (JCPDS card No. 41-1449) using the XRD technique. Our finding also support the synthesis of CuO NPs from Iranian violaceae flower sources due to relative abundance of plants for the production of reducing and stabilizing agents required for CuO NPs synthesis, potential efficiency of plant biomolecules in enhancing the toxicity effect of CuO NPs against microbes, prevention of environmental pollution due of nontoxic chemicals and degradation effectiveness of CuO NPs synthesized from plant sources. Furthermore, this study provides useful information on the rapid synthesis of CuO NPs with desired properties from plant extracts. Copper oxide NPs can have a good candidate for different applications.
